Algebra is a challenge for teachers and students alike. Teachers have their hands full trying to focus on key concepts while imparting procedural knowledge, relating algebra to arithmetic, and connecting it to real-world experiences.

The Xs and Whys of Algebra is an 84-page flipchart that cuts through the confusion to help you prevent common misconceptions. Following the same practical format as their popular Zeroing in on Number and Operations series, Anne Collins and Linda Dacey provide 30 modules that focus on key ideas with instructional strategies, activities, and reproducibles for:
• using variables meaningfully;
• using multiple representations for expression;
• connecting algebra with number;
• connecting algebra with geometry; and
• manipulating symbols with understanding.
All teachers of algebra should have this handy flipchart at their fingertips during planning and instruction. You can preview two of the modules—Systems of Linear Inequalities and Posing Problems for Inequalities—online now.
